Denton County is the 25th fastest-growing county in United States with nearly 781,000 residents, according to the U.S. Census Bureau. Effective September 1, 2001, Denton County Transportation Authority (DCTA) was enabled by House Bill 3323 during the 77th Texas Legislature. Senator Jane Nelson and Representative Burt Solomons worked closely with the Denton County Commissioner’s Court and community leaders to pass H.B. 3323, initiating the process to create the authority. On November 5, 2002, Denton County approved the creation of DCTA to advance public transportation alternatives. DCTA was funded in 2003 by a dedicated half-cent sales tax from the cities of Denton, Lewisville and Highland Village and fulfilled its initial service plan in June of 2011 with the launch of its A-train commuter rail service.
We’re committed to improving mobility, air quality, economic development and livability in the areas we serve. For the past 17 years, DCTA has accelerated innovative transportation solutions which have been critical to reducing traffic congestion and enhancing air quality, while contributing to orderly growth and development and improving the quality of life for Denton County residents.
